- CD Player Service Precautions

1.For pickup unit(CXX1480) handling, please refer to"Disassembly"(see page 41).

During replacement, handling precautions shall be taken to prevent an electrostatic discharge(protection by a jumper-solder).

2.During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged.

3.Please checking the grating after changing the pickup unit(see page 38).

4.In this product, because the memory capacity of the microcomputer is insufficient, the test mode is not installed. However grating of the pickup unit can be confirmed.

1. SAFETY INFORMATION

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual.

1. Safety Precautions for those who Service this Unit.

•When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.

Caution:

1.During repair or tests, minimum distance of 13cm from the focus lens must be kept.

2.During repair or tests, do not view laser beam for 10 seconds or longer.

2.A “CLASS 1 LASER PRODUCT” label is affixed to the bottom of the player.

3.The triangular label is attached to the mechanism unit frame.

CLASS 1

LASER PRODUCT

4. Specifications of Laser Diode

NOTE :

Symbol indicates a resistor.

No differentiation is made between chip resistors and discrete resistors.

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and discrete capacitors.

The > mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation.

For resistors and capacitors in the circuit diagrams, their resistance values or capacitance values are expressed in codes:

Ex. *Resistors
Code	Practical value
123	12k ohms
103	10k ohms
*Capacitors
Code	Practical value

	The > mark found on some component parts indicates
	the importance of the safety factor of the part.			7
	Therefore, when replacing, be sure to use parts of
	identical designation.
	For resistors and capacitors in the circuit diagrams, their resistance values or
	capacitance values are expressed in codes:
15a-A 87	Ex. *Resistors		A		1400R,1400RB,1430R-DEH	87
	Code	Practical value
	123	12k ohms
	103	10k ohms
	*Capacitors
	Code	Practical value
	103	0.01 F
	101/10	100 F/10V
